Abstract : A discussion is given of efforts to understand in atom terms how spontaneous polarization arises in the ferromagnetic substances, lithium hydrazinium sulfphate(Li(N2M5)SO4) and colemanite(CaB3O4(OM)3.H2O). The 7Li and 11B nuclear magnetic resonance was used as a probe to study the structure of these ferroelectrics under varying conditions.
